JOHN S. DICKEY, OF ETHEL, TEXAS.

CHURNI-POWER.

SPECIFICATION formingpart of Letters Patent No. 655,765, dated August 14, 1900. Application filed February 19, 1900. Serial No. 5,847. (No model.)

To all whom it mayconcern:

Be it known that 1, JOHN S. DIOKEY, a citizen of the United States, residing at Ethel, in the county of Grayson and State of Texas, have invented a new and useful Churn-Power, of which the following is a specification.

The invention relates to improvements in churn-powers.

The object of the present invention is to improve the construction of churns and to provide a simple and comparatively-inexpensive one which will be strong and durable and which will be capable of thoroughly agitating its contents and quickly producing butter at the expenditure of a minimum amount of labor. 7

The invention consists in the construction and novel combination and arrangement of.

parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a'perspective view of a churn constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a horizontal sectional View.

Like numerals of reference design ate corresponding parts in all the figures of the drawlugs.

1 designates a supporting-frame provided with a substantially T-shaped base composed of a longitudinal bar 2 and an end transverse bar 3, centrally secured to one end of the central longitudinal bar 2. From one'end of the central longitudinal bar 2 rises an upright or post 4, which is connected at its upper end by a top bar 5with a pair of parallel uprights or bars 6, spaced apart and arranged at opposite sides of the central longitudinal bar 2, as clearly illustrated in Fig. 3 of the accompanying drawings. The uprights or bars 4 and 6 and the horizontal top bar form, with the central longitudinal bar, a rectangular framework, which is supported by a pair of inclined braces 7, spaced apart similar to the uprights 6 and extending upward from the adjacent end of the central longitudinal bar 2 to the upper ends of the uprights or bars 6, being preferably secured to the adjacent end of the top bar 5.

The central longitudinal bar of the supporting-frame is provided at the center of the space between the uprights 4t and 6 with a bearing for the reception of a lower journal 8 of a rotary frame 9, which is provided with an upper journal or spindle 10, extending through a bearing-opening of the top bar 5 and projecting above the same, whereby it is adapted to carry a fan, which will be operated simultaneouslywith the churn. The rotary frame, which is rectangular, as clearly shown in Fig. 2, may be constructed in any suitable manner, and it is provided with a circular table or support 11, mounted upon the bottom cross bar of the rotary frame and adapted to receive a churn-body 12. The churn-body 12, which may be of any desired construction, is retained on the table or support of the rotary frame by means of a piv otedbutton 13 and a curved bar 14, of substantially-semicircular form, secured at its ends to the inner faces of the sides of the rotary frame and forming a back for the table or support. The churn-body is placed upon the table or support and is fitted tightly against the curved bar or piece 14, and it is secured in this position by the button, which is turned against the front of the churn-body. The churn-body is provided with a solid cover 15 to exclude flies and to prevent the contents from being thrown out of the body, and the latter is provided on its interior with vertical slats or cleats 16, and it has a bottom slat or cleat 17. The vertical slats or cleats are arranged at intervals in an annular series and are provided with projecting ribs similar to that of the bottom slat or cleat, and the con tents of the churn-body coming in contact with the slats or cleats are thoroughly agi tated and butter is quickly produced.

The rotation of the frame 9 is effected by means of a lever 18, fulcrumed between its ends at 19 between the inclined braces and connected at its upper portion with the upper journal of the rotary frame by a cord. or belt 20 and having its lower end connected with a coiled spring 21. The upper end of the. operating-lever, which extends above the supporting-frame, is shaped into a handle, and the pivot upon which the lever is fulcrumed passes through the inclined braces. The up per journallO is provided between the supporting and the rotary frames with a vertical is adapted to be wound around the upper journal between the rotary frame and the supporting-frame, and it passes therefrom between the uprights 6 and the braces to the operating-lever, being preferably secured to the same in a perforation thereof; but any other suitable means may be employed for connectingthepartsat thispoint. Thecoiled spring is arranged in ahorizontal position at a point above the central longitudinal bar of the base of the frame, and its outer end is linked into a perforation 24 of the lower end of the operating-lever, its inner end being provided with an eye 25 and being secured to the supporting-frame by a bolt or pin 26, which passes through the lower portions of the upright 6.

When the operating-lever is oscillated, the

- rotary frame is reversibly rotated, the adjacent end of the flexible connection being alternately wrapped around the upper journal 10 and unwound therefrom, and the coiled spring at the lower end of the operating-lever assists the return of the same. When the churn is in operation, the weight of the conincreases the power of the churn, and the momentum just acquired operates to rotate the churn-body rapidly and is counteracted by the coiled spring, which is gradually distended until its power is sufficient to check the rotation of the rotary frame. The flexible connection is wound around the upper journal of the rotary frame when the coiled spring is distended, and it is unwound therefrom by the action or contractile power of the spring, thereby producing a reversal of the rotation of the rotary frame. After the churn has been put in motion and a high rate of speed is attained the operating-lever may be released by the operator and the operation of the churn will continue for some time, and it is adapted to be operated at the expenditure of a minimum amount of power.

It will be seen that the rotary movement of the churn-body produces a thorough agitation of its contents, that butter is rapidly produced, and that by dispensing with a dasher the cover may be made imperforate and will prevent cream from splashing from the body and at the same time will exclude flies therefrom. It will also be apparent that the weight of the rotary frame, the churnbod-y, and the contents thereof operate to increase the effect of the churn instead of retarding the action of the same, as would be the case were a dasher simply rotated instead of the entire churn-body. Furthermore, it will be clear that the agitation of the contents of the churn-body will be materially increased by the fact that the said churn-body is eccentrically arranged on the table or support of the rotary frame, as clearly illustrated in Figs. 1 and 3 of the drawings.

I hat is claimed is 1. The combination of a supporting-frame, a rotary frame having a spindle and adapted to receive a churn-body, a lever fulcrumed between its ends on the supporting-frame, a spring connected with one arm of the lever, and a flexible connection secured at one end to the other arin of the lever and having its other end wound around the spindle of the rotary frame and adapted to be unwound therefrom, substantially as described.
